SPECIFICATION forming part of Letters Patent No. 772,187,

dated October 11, 1904.

Application filed September 5, 1903. Serial No. 172,101. No model.)

To all whom it may concern.-

Be it known that I, HUBERT H. TA'rsoH, a citizen of the United States,and a resident of Fredericksburg, in the county of Gillespie and Stateof Texas, have invented new and useful Improvements inWindmill-Lubricators, of which the following is a full, clear, and exactdescription.

This invention appertains to an improved lubricating device, and hasparticular application to a lubricator designed especially for use inconnection with windmills.

An object of my invention is to provide a lubricator adapted atpredetermined times to supply a lubricant to a receptacle, from whichreceptacle ducts lead off the lubricant to the portions of the windmillto be subjected to the lubricating process. p

A further object of my invention is to provide a device which will beautomatic in its operation-that is to say, the lubricating operationwill not take place until certain mechanism actuated from themill-pitman isbrought into operation to supply the receptacle, abovereferred to, with the lubricant.

Still another object of the invention is to provide a lubricator whichis so incased or housed that the possibility of dust, ice, snow, or thelike clogging or otherwise interfering witgli the operation of the partswill be obviate Finally, 'I have in view as an object to provide alubricator which will be exceedingly simple and durable in itsconstruction, positive in its operation, and capable of being readilyattached to any windmill.

With the above-recited objects and others of a similar nature in view myinvention consists in the construction, combination, and arrangement ofparts, as is described in this specification, delineated in theaccompanying drawings, and set forth in the appended claims.

a lubricator shown in Fig. 1. Fig. 3 is a detail view, partly insection, showing the position of certain parts of the mechanism designedto supply lubricant to the receptacle from which it is conveyed to theparts of the mill; and Fig. 4: is a detail view, partly in section, of aportion of the bucket designed to convey the lubricant to thereceptacle.

Referring now to the accompanying drawings in detail, 5 designates theshank of a bifurcated bracket, the arms6 6 of such bracket beingdesigned to be secured to the main casing 7 of the device. Dependingfrom the base portion 8 of the aforesaid casing is a hanger 9, havingformed in the parallel side bars thereof the registering apertures 1010,which are designed to receive and support a cross-bar 11, held inposition by means ofacotter-pin 12. Adapted to rest upon this bar is arelatively long lever 13, pivoted at 14: to one end of the arm 15, saidarm in turn resting upon the pitman of the windmill. (Not shown.) Theopposite end of the lever 13, which is formed with a bifurcation 16, isloosely mounted on a shaft 17 journaled in the base portion 8 of thecasing. Upon this shaft is fixed a gearwheel 18, the periphery of saidWheel having about fifty teeth out therein, said teeth being normallyengaged by a gravity-pawl 19, pivoted at 20 between the arms of thebifurcated portions of the lever 13. Suspended at 21 from a pointslightly above the gear-wheel 18 is a second weighted gravity-pawl 22,designed to engage with the teeth of the gear-wheel to prevent suchgear-wheel turning'back after it has been given a forward lmpulse ormovement when the lever 13 is lowered by the action of thewindmill-pitman, for, as will be noted,'this movement of the lever 13causes the pawl 19 to rise and drop into the next notch in the wheel 18,said movement giving the wheel a backwardimpulse. There is also mountedupon the rotating shaft 17 a wormgear 23, designed to engage or meshwith a horizontally-disposed toothed gear-wheel 24, carried by thevertically-arranged shaft 25. This shaft 25, which extends up throughthe casing to approximately centrally of the interior, has at such upperend a worm-gear 26,

meshing with a gear-wheel 27, journaled upon the shaft 28, extendingtransversely of the casing. hen the shaft 25 is turned through the lowerintermeshing gear-wheels, the worm at the upper end thereof will drivethe gearwheel 27, which gear-wheel has secured thereto, through themedium of a screw 29, an arm 30, such arm having pivotally connectedthereto at its outer end 31 a cup or bucket 32. This bucket is intendedto take up a portion of the lubricant A, placed in the body of thecasing, and as the gear-wheel 27 is revolved said bucket will moveupward and be directed in its path of movement by the curvedguiding-strip 33, arranged adjacent to the side of the casing, saidstrip being approximately semicircular in conformation, the bucket beingguided with relation to said strip through the medium of the guide-pins34 35, secured to the bucket one at each side of said strip.

When said cup or bucket has reached the upper end of the strip, themovement of the wheels still continuing, the guide-pins will pass theend of the strip, and the bucket, no longer sustained, will swing ordrop down through gravity upon its pivot-point, as is clearly seen indotted lines in Fig. 2. The lubricant contained in suchbucket will thenbe poured into a box-like receptacle 36, arranged at one side of thecasing. The bottom 37 of said receptacle is downwardly inclined, andleading therefrom at its lower end are a number of tubular oil pipes orducts 38, which projecting through the side of the casing convey the oilfrom the receptacle to any suitable point on the windmill. For example,in Fig. 1 I have shown a conical cup 39, designed to receive oil fromone of the pipes, said cup having a ball-valve 40 near the lower endthereof, the stem 41 of said valve being designed to be connected withthe crankshaft of the windmill, so that on each movement of saidcrank-shaft the ball-valve will move upward and permit oil to drop uponthe parts of the windmill to be lubricated. After the bucket 32 has beenemptied it continues its circular path of travel and is immersed in theoil, the bucket is again filled, and the operation is continued.

It is to be noted in particular that the frequency with which the bucketof oil at the end of the arm is emptied in the receptacle 36 dependsentirely upon the gearing mechanism that is to say, if the gear-wheel 18has fifty teeth, and asimilar number of teeth are formed on thehorizontal gear-wheel 24 and the upper gear-wheel 28, the bucket willmake one complete revolution with every one hundred and twenty-fivethousand strokes of the pitman of the windmill, inasmuch as it will beobserved that the gear-wheel 24 will only be moved one tooth with everycomplete revolution of the shaft 17 It will further be seen that the bar11, carried by the hanger 9, may be placed higher or lower therein toregulate the throw of the lever 13, and consequently alter the frequencywith which the windmill will be lubricated.

The casing of the device, which is approximately cylindrical in form, ismade up in two parts, the upper of which is hinged at 4:2 to thelowersection, so that such upper section may act as a cover protecting theparts from dust, and yet enable the lubricant to be readily supplied tothe casing. The cover may be locked in any suitable manner, such as bythe pin 43 engaging with the hasp 44 and plates 15, as will be clearlyseen in Fig. 1.

From the above description the construction and operation of my improveddevice will be readily apparent, and it is unnecessary to furtherdescribe the same here in detail. This device will be found especiallyadapted for use in large windmills, where it is diflicult to obtainaccess to the various parts for the purpose of lubrication.
